Show probe name in detector progress bar

[feiiiiii5]

What

The detector progress bar previously showed only detectors.<name> in its
description, leaving users unable to tell which probe's results were being
checked when multiple probes share the same detector in a single run.

This change prepends the probe name to the description, producing e.g.
probes.test.Blank/detectors.always.Pass.

Fixes #324

Why

Issue #324 reports that the probe name is hidden in the detector tqdm
description. In a multi-probe run with shared detectors, the progress bar
gives no indication of which probe is currently being processed, so the user
cannot track progress through the run.

Approach

• Capture probe.probename.replace("garak.", "") once per probe (matching
  the pattern already used in garak/probes/base.py:325,363) and prepend it
  to the existing detector description using a / separator. This separator
  matches the precedent in garak/buffs/base.py:84
  (f"📥 Buffing probe: {probename}/{self.fullname}").
• Both ProbewiseHarness (harnesses/probewise.py:110) and PxD
  (harnesses/pxd.py:60) delegate to base.Harness.run() via
  super().run(), so a single change in base.py covers all harness
  variants.
• No new dependencies, no API changes, no changes to attempt/detector/base
  classes.

  touch garak/harnesses/base.py despite description mentioning it)

PR #1718 (open, 2026-04-27, "Log detector skip info", fixes #1061) also
touches garak/harnesses/base.py but modifies the if d.skip: block
(lines 162-175) and appends a _log_detector_skip_info() function. This PR
modifies only the set_description call (line 200) and adds one line before
the for d in detectors: loop (line 194). The changes are non-overlapping
and git auto-merges cleanly.

Verification

• python -m pytest tests/harnesses/test_harnesses.py -v → 4 passed
• python -m pytest tests/test_internal_structures.py -v → 17 passed
  (adjacent suite — tests harness plugin cache behavior)
• python -m black --check garak/harnesses/base.py tests/harnesses/test_harnesses.py
  → clean (line-length 88)
• Visual check: python -m garak -m test -p test.Blank -d always.Pass -g 5
  shows probes.test.Blank/detectors.always.Pass: 0%|... in the detector
  progress bar
• Regression test test_harness_detector_progress_shows_probe_name wraps
  tqdm.tqdm to capture set_description calls and asserts both
  probes.test.Blank and detectors.always.Pass appear in the description
• python -m pytest tests/ — full suite hangs at collection time on this
  machine (garak's plugin imports require network/optional dependencies
  not available locally; PR Log detector skip info #1718 reports the same issue). Targeted
  relevant subsets (harnesses, internal_structures) all pass.

Hi @jmartin-tech — noting that the CI failures on the ubuntu/macos jobs are from tests/probes/test_probes_dra.py::test_dra_moderation_cache_loaded, which fails with:

OSError: Can't load the configuration of 'bert-base-uncased'

The CI log shows this is a HuggingFace ReadTimeout during model download (ubuntu/macos runners hit network timeouts; the equivalent windows job passed). This is unrelated to the changes in this PR — I only touched garak/harnesses/base.py (4-line set_description change) and tests/harnesses/test_harnesses.py (regression test), and all 4 harness tests pass. The DRA probe's bert-base-uncased download is a pre-existing network dependency.

The force-push to fix a missing DCO signoff on the rerun-trigger commit set the workflow runs to action_required. Could you approve the CI rerun (or gh run rerun --failed on the affected jobs) when you have a chance? Thanks.

Testing for land is queued, I removed the empty commit and triggered CI tests. If there is another intermittent failure a maintainer will clear it.

Thanks @jmartin-tech for the update and for clearing the empty commit — appreciate the hand on the intermittent CI failure. Standing by if anything else is needed.

Hi @jmartin-tech — gentle nudge on this one. CI has been green (CLEAN state) since 7/16, just confirming whether anything is still needed on my side before this can be merged. Happy to rebase or address any final feedback. Thanks!

Follow-up to my earlier ping — I dug into the two failing build jobs and confirmed they are both HuggingFace download timeouts, not code regressions:

build (ubuntu-latest, 3.10) — bert-base-uncased ReadTimeout

• Failing test: tests/probes/test_probes_dra.py::test_dra_moderation_cache_loaded[probes.dra.DRAAdvanced]
• Error: OSError: Can't load the configuration of 'bert-base-uncased'... wrapped around httpcore.ReadTimeout: The read operation timed out while fetching bert-base-uncased/config.json from HuggingFace Hub
• 4606 passed, 1 failed

build_macos (3.13) — audio_achilles_heel dataset ReadTimeout

• Failing test: tests/plugins/test_plugin_load.py::test_instantiate_probes[probes.audio.AudioAchillesHeel]
• Error: httpx.ReadTimeout: The read operation timed out (wrapped as GarakException) while fetching the garak-llm/audio_achilles_heel dataset README from HuggingFace
• 4607 passed, 1 failed

Comparison with main

The PR check ran on 2026-07-11 (9 days ago, stale). Since then:

• main nightly run on 2026-07-19 (run 29666757364): SUCCESS — all jobs passed including both build (ubuntu-latest, 3.10) and build_macos (3.13)
• main nightly run on 2026-07-20 (run 29709377902): FAILURE — but only build_macos (3.10/3.12/3.13) failing at the Set up Python step with candidates is not iterable (a GitHub Actions setup-python infra issue), not the same HF timeout pattern

So the PR failures were transient HuggingFace network flakiness at the moment of the 7/11 PR run. The same code paths exist on main and would intermittently fail there too whenever HF Hub is slow. The 9213 passing tests vs 2 timeouts and mergeStateStatus=CLEAN confirm this doesn't block merge.

Recommended action: re-run the two failing jobs (or the whole workflow) — they should pass against the current HF Hub state. Happy to do that myself if you can authorize the fork-PR workflow runs.
